2-6 Kennedy Valve/Hydrants
ELBoW – We must have the size and type of connection to main.oPErATinGsTEMnUT – Give direction to open (cast on cap) and size and shape of operating nut. 4-sided nut, give flat to flat dimension. 5-sided nut, give point to opposite flat dimension. 6-sided nut, give flat to flat dimension to eliminate any doubt as to where the measurement was taken.*Note: Dual rated hydrants are UL/FM approved for 11/2P and 11/4” sq. nut sizes.
cAp – Give direction the hydrant opens. This is indicated by an arrow cast on the cap. Indicate the direction the arrow points.nozzLE CAP GAsKET – Indicate size of nozzle and whether hose or steamer.nozzLE – Give exact threading details, outside (major) diameter, pitch diameter, root (minor) diameter and exact number of threads per inch (TPI) or send in a gauge or sample in good condition.
6. Color (National standard yellow will be furnished unless otherwise indicated).
7. Size and shape of operating nut.8. Direction to open.9. Regular or Bronze Lined (for Mathews-Guardian Insert only).
Guardian HydrantWhen ordering, indicate the following:1. Size of main valve opening.2. Quantity and threading details of hose nozzles.3. Threading details of steamer nozzle.4. Size and type of inlet connection (mechanical joint, flanged,
asbestos-cement, bell, or tyton).5. Depth of bury (from bottom of pipe to ground line).
partsWhen ordering parts, indicate the following:1. Part number2. Part description3. Type of hydrant4. Size of main valve opening
nozzLECAPCHAin –Tell us the nozzle type, hose or steamer.nozzLECAP – Exact threading and nut size and shape.UPPErBArrEL – Furnish all information cast on the barrel and the number of hose and steamer connections.sTEM – Furnish the direction the hydrant opens as cast on the cap and furnish the depth of trench (distance from groundline to bottom of connecting pipe). If the stem can be measured, complete overall dimensions including diameter will help. The diameter should always be measured on the smooth (unthreaded) portion.*LoWEr BArrEL – Furnish depth of trench (distance from groundline to bottom of connecting pipe) or dimension from flange face to flange face (overall). The outside and inside diameters are also a help.sEATrinG – As with all parts you order we must have size of main valve opening and type of hydrant. This is cast on the upper barrel.
